Member Function Documentation

current_status()

rs2_playback_status rs2::playback::current_status ( ) const

inline

Returns the current state of the playback device

Returns

Current state of the playback

file_name()

std::string rs2::playback::file_name ( ) const

inline

Retrieves the name of the playback file

Returns

Name of the playback file

get_duration()

std::chrono::nanoseconds rs2::playback::get_duration ( ) const

inline

Retrieves the total duration of the file

Returns

Total duration of the file

get_position()

uint64_t rs2::playback::get_position ( ) const

inline

Retrieves the current position of the playback in the file in terms of time. Units are expressed in nanoseconds

Returns

Current position of the playback in the file in terms of time. Units are expressed in nanoseconds

is_real_time()

bool rs2::playback::is_real_time ( ) const

inline

Indicates if playback is in real time mode or non real time

Returns

True iff playback is in real time mode

pause()

void rs2::playback::pause ( )

inline

Pauses the playback Calling pause() in "Paused" status does nothing If pause() is called while playback status is "Playing" or "Stopped", the playback will not play until resume() is called

resume()

void rs2::playback::resume ( )

inline

Un-pauses the playback Calling resume() while playback status is "Playing" or "Stopped" does nothing

seek()

void rs2::playback::seek ( std::chrono::nanoseconds time )

inline

Sets the playback to a specified time point of the played data

Parameters

[in]

time

The time point to which playback should seek, expressed in units of nanoseconds (zero value = start)

set_playback_speed()

void rs2::playback::set_playback_speed ( float speed ) const

inline

Set the playing speed

Parameters

[in]

speed

Indicates a multiplication of the speed to play (e.g: 1 = normal, 0.5 twice as slow)

set_real_time()

void rs2::playback::set_real_time ( bool real_time ) const

inline

Set the playback to work in real time or non real time

In real time mode, playback will play the same way the file was recorded. In real time mode if the application takes too long to handle the callback, frames may be dropped. In non real time mode, playback will wait for each callback to finish handling the data before reading the next frame. In this mode no frames will be dropped, and the application controls the frame rate of the playback (according to the callback handler duration).

Parameters

[in]

real_time

Indicates if real time is requested, 0 means false, otherwise true

Returns

True on successfully setting the requested mode

set_status_changed_callback()

template<typename T>

void rs2::playback::set_status_changed_callback ( T callback )

inline

Start passing frames into user provided callback

Parameters

[in]

callback

Stream callback, can be any callable object accepting rs2::frame Register to receive callback from playback device upon its status changes

Callbacks are invoked from the reading thread, and as such any heavy processing in the callback handler will affect the reading thread and may cause frame drops\ high latency

Parameters

[in]

callback

A callback handler that will be invoked when the playback status changes, can be any callable object accepting rs2_playback_status

stop()

void rs2::playback::stop ( )

inline

Stops the playback, effectively stopping all streaming playback sensors, and resetting the playback.
